to this rule is ROM terminal definition tables addresses are constant. Therefore, ifonly ROM terminal types are bound to ports, there will not be a need for regeneratingthe ports due to reassembly of the image file. 7171MPRT is much easier touse for sites which will change TDTs or Port definitions frequently.C.13.1 Updating the 7171 PortsThere are 5 steps involved in updating the ports when using 7171PORT:1. Get the current Image file. This could be a newly generated image file from7171 LINK, 7171 MLNK, or an image file stored in the 7171. If this is a newimage which is not in NV -RAM, it is important that the terminal definitions areloaded before the ports.2. Load the Image data.3. Configure the Ports.4. Save the reconfigured Ports.5. Transmit the Image file to the IBM 7171 through the 110 function.There are 4 steps involved in updating the ports when using 7171MPRT:1. Create a Port Profile, or update an existing profile.2. Get the current Image file. This could be a newly generated image file from7171LINK, 7171MLNK, or an image file stored in the 7171. If this is a newimage which is not in NV -RAM, it is important that the terminal definitions areloaded before the ports.3. Invoke the 7171MPRT processing specifying the port profile and the image filewhich will be stored in the 7171.4. Transmit the Ports Image file to the IBM 7171 through the 110 function,TERMS then PORTS.C.14 Entering a New Terminal TableC.14.1 Generating a Completely New Terminal TableIf the user is going to generate a new table, the following steps are involved:1.
